In both Debian and Ubuntu, only the main repo gets official security updates for free. Ubuntu has a paid option for universe whereas Debian doesn't have that option and relies on the package maintainer to provide any updates.
I'd still recommend Debian over Ubuntu though, for various reasons.
Package maintainers can be slow to update packages though. Debian have a separate security team that get patches out ASAP, and those packages go into a separate security repo. I imagine Ubuntu does the same. It's that security team that only deals with "official" packages, meaning anything that's not in contrib, non-free, or non-free-firmware.
What you're paying extra for are timely security updates for community-maintained packages that aren't an official part of the OS. Debian doesn't provide that for free either. Debian doesnt provide it at all since they don't have any paid options.
No. All the official packages in the main repo get security updates from the Debian security team.
Only the packages in contrib, non-free and non-free-firmware don't have official security updates and rely on the package maintainers. These are not considered part of the Debian distro, and I don't even have them enabled on my servers.
Out-of-the-box, Debian only enables the main repo, plus the non-free-firmware one if any of your devices require it (e.g. Nvidia graphics, Realtek Bluetooth, etc). You have to manually enable contrib and non-free, and by doing that, it's assumed you know what you're doing.
In the case of non-free and non-free-firmware, they can be closed source software (like the Nvidia drivers) or have a non-open-source license that doesn't allow distributing modified versions. In those cases, the Debian team is unable to patch them even if they wanted to.

Do users get the package maintainer's updates for free?
Definitely on Debian, and I think on Ubuntu too.

To me, it looks like Debian and Ubuntu are both secure but you have to pay extra to make Ubuntu at least as secure as Debian.
